Specification of Letters Patent.

Patented Oct. 17, 1911.

Application filed August 23, 1909. Serial No. 514,206.

To all whom it may concern:

Be it known that I, LEWEN R'NELsoN, citizen of the United States,residing at Peoria, in the county of Peoria and State of Illinois, haveinvented certain new and useful Improvements in Nozzles; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itappertains to make and use the same.

This invention pertains to improvements. in hose nozzles.

An important object of the invention is to materially simplify andcheapen the construction of a hose nozzle. Also to provide a nozzlewherein the parts are all held in position without the employment ofscrews or other unnecessary parts.

An object also is to provide a nozzle wherein a valve which governs thedischarge of water is placed upon an apertured portion of the nozzle andheld in position by means of the usual washer or gasket and a threadedmember carried by the hose or by some part that will answer in the samecapacity.

Another object is to provide a nozzle in which said threaded member, orother member, will serve to hold all of the parts of the nozzle togetherbut this will be clearly pointed out in the following specification.

Still another object is to provide a nozzle whose parts can be formedfrom tubing.

A preferred embodiment of myinvention is illustrated in the accompanyingdrawings, in which Figure 1 is an elevation of the hose nozzle shown inits natural size. Fig. 2 is a longitudinal section of the nozzle greatlyenlarged. Fig. 3 is a plan of the inner rear end of a stem of thenozzle. Fig. 4: is an elevation of the rear end of the nozzle and partsshowing a form of valve used therewith. Fig. 5 is a plan of another formof valve, and Fig. 6 is a plan of the same form of valve but of a largersize.

Referring to the drawings, it will be seen that the nozzle comprises astem A which consists preferably of a piece of tubing internallythreaded at its outer or forward end to receive a flared tip B providedwith a discharge opening C, its other or rear end having an annularflange D formed up upon it and counterbored at E, Figs. 2 and 5 toreceive a valve F having perforations G, there being two of suchapertures and disposed diametrically opposite one another. Said valvemay be a part of the stem A, however, and may have but one aperture.

H represents a sleeve which may be a casting, or spun from sheet metal,and provided. with a bore J substantially of the same diameter as thestem and adapted to receive that member. Said sleeve is counterbored atK and receives the flange D of said stem and has a surface parallel tothe rear face of the stem as at K in Fig. 2 and said sleeve has a largethreaded bore as indicated at L to receive the usual fitting M carriedby the hose indicated at N.

Resting against the valve F described is a member O which I term avalve. This valve-seat as shown in Fig. 5 may be a mere duplicate of thevalve F both as to size and form or it may be larger in diameter as inFig. 6 so as to fit into the threaded bore L, or as shown in Fig. 4; atP, it may bein the form of two connected segment-shaped parts each ofwhich is large enough to cover one of the apertures G of the said valveF. The valve-seat may be pivoted to the valve by means of a pivot-pin Q,but I may not use said pivot-pin, merely placing the valveseat, upon theplate F as shown in Fig. 4, and upon this is placed an ordinary ring orgasket or annulus R of rubber or other yielding material the hole orbore of which may be slightly less in diameter than the diameter of thevalve-seat as shown in Figs. 2 and 4-so as. to partially overlie it; thefull diameter of said gasket being such as to fit into the largest orthreaded bore of the sleeve as shown, or said hole or bore may besubstantially of the same diameter as the valve-seat of the form shownin Fig. 4: at P whose periphery may have a series of lugs or points S asshown to embed themselves in the rubber either method providing forfriction between the said gasket and the valve seat to hold the latter.

The fitting M before described when screwed into the sleeve bearsagainst the ring or gasket R and forces it against the marginal portionof the valve-seat or upon said lugs S, as the case may be, and saidvalve-seat can thus be centrally held in position and is also held fromturning since the friction that must exist between the gasket and thevalve-seat is greater than that between the latter and the plate F whichlie upon one another. Other means for holding the fitting M, or itsequivalent, within the sleeve may be resorti or . or open portions ofsaid valve-seat and thus the amount of discharge and the form thereofcan be governed, 2'. 6. whether a stream or spray.

The friction imposed upon the stem A through the gasket is regulated byscrewing the member M more or less tightly in place in the sleeveagainst said gasket B so that the said stem can be turned more or lesseasily. The form of valve seat in Figs. 2 and 5 as already stated can bea mere duplicate of the valve F in Fig. 3 and can be made of much largerdiameter so that it. will fit into the large threaded bore of the sleevein the same manner as the gasket R and when made of a yielding materialwill answer both as the gasket and the valve-seat.

The nozzle is easily and quickly assembled :The stem is dropped into thebore of the sleeve and the valve-seat is then placed centrally upon therear end of said stem, after which the gasket R is inserted and thefitting M screwed into place against it, or, in lieu of the valve-seatand gasket, the comf bined valve-seat and gasket shown in Fig. 6

is used. It is to be noted that no screws or rivets are necessary tohold the parts together since the members are secured firmly in properrelation by merely screwing the hose fitting M into the sleeve althoughsome other means that will serve to hold the parts togethersubstantially in the same way may be used although the member Mdescribed is perhaps preferable.

When the member shown in Fig. 6 is employed there is one part less usedin the construction of the nozzle although the effect of both the gasketand valve-seat is obtained. It is clear that the advantage of simplicityof construction and consequent cheapening must result in producing anozzle of the form described and I believe that the way in which thenozzle is assembled is new when the fitting M orsome other member havingthe same purpose in view is used as the holding member for all of theparts.

A point of importance in my nozzle is that the sleeve H has an annularface beyond and surrounding the outer marginal edge of the stem so thatthe gasket can lie upon it and properly overlie the joint between it andthe stem and thus prevent leakage through said joint. Furthermore, bymaking the valve smaller 1n diameter than the rear end of the stem 'thegasket will overlie the marginal edges of both of them and hold theformer so that the stem must turn independently of it.

Of importance, also, is the fact that the gasket overlies a considerableportion of the said marginal edge of the stem beyond the margin of thevalve insuring thereby that the joint above mentioned will be properlyand thoroughly covered and protected againstthe leakage mentioned.
